基于 Realtek RTL8221B 2.5G ETHERNET TRANSCEIVER WiFi6路由器 AX5400M 設(shè)計(jì)方案

2.5GbE主要優(yōu)勢(shì)如下：

1. 體積縮小64%、省電50%更環(huán)保:
QFN封裝的尺寸比上一代更小，以全速2.5G傳收時(shí)僅需0.65瓦的耗電，體積更小并降低散熱處理的成本，非常適合搭載于輕薄短小的行動(dòng)裝置，將連結(jié)更高速行動(dòng)網(wǎng)路的市場(chǎng)需求。

2. 高速、高穩(wěn)定性、高相容性：
經(jīng)專業(yè)網(wǎng)路測(cè)試工具證實(shí)，與市面各大網(wǎng)路交換器連接，能穩(wěn)定地維持高速雙向傳輸(上傳與下載)。支援比標(biāo)準(zhǔn)規(guī)格更長(zhǎng)10%網(wǎng)線 穩(wěn)定傳輸: IEEE802.3bz定義2.5GbE需支援Cat 5e網(wǎng)路線長(zhǎng)標(biāo)準(zhǔn)為100米，而瑞昱網(wǎng)卡可支援更長(zhǎng)至110米，不讓線長(zhǎng)工差吃掉網(wǎng)路品質(zhì)，且即便網(wǎng)路線分段串接，也能保持優(yōu)越的效能，在復(fù)雜的網(wǎng)路串線環(huán)境下，能維持效能不衰減。
